Abstract
In a marking device for marking an information carrying medium, a marking tip is provided on an arm, and the arm is resiliently mounted by means of a leaf spring. In order to relieve stresses on the joints between the leaf spring and the arm, a region of the leaf spring to which the arm is affixed is bent, so that one portion of the leaf spring is affixed to the side of the arm toward the information carrying medium, and another portion of the leaf spring is affixed to the opposite side of the arm.
